Department of Homeland Security nominee Mullin faced scrutiny during a Senate confirmation hearing over workforce reductions at the Cybersecurity and Infrastructure Security Agency (CISA). The questioning centered on decisions made following the Trump administration's return to office.
Senator Maggie Hassan pressed Mullin on cuts implemented under Kristi Noem's leadership that reduced CISA's workforce by one third. The reductions also included removing hundreds of millions of dollars from the agency's operational budget, raising concerns about the agency's capacity to fulfill its cybersecurity mission.
